STEAM AND OILl SEPARATOR.

SPECIFICATION forming part of Letters Patent N o. 699,691, dated May 13,1902.

Application filed November 9, 1901. Serial No. 81,733. (No modela Toa/ZZ whom t may concern:

Be it known that I, JOHN T. LINDSTROM, a citizen of the United States,residing at Allentown, in the county of Lehigh and State ofPennsylvania, have invented new and useful Improvements in Steam and OilSeparators, of which the following is a specification.

Myinvention has relation toimprovements in steam and oil separators ofthat kind particularly adapted for association with and connection to asteam-engine cylinder, whereby the exhaust-steam may be separated fromthe oil or lubricant and purified for subse-` quent use and return tothe boiler.

The object of the invention is to provide an apparatus or device of thekind named and for the purpose mentioned which is of simplified andimproved construction and which of the purposes.

I have fully and clearly illustrated the invention in the accompanyingd1'awings,whe1e 1n- Figure l is a View in elevationshowing a steamcylinder of a steam engine with my improved steam and oil separatorconnected to the exhaust-pipe. Fig. 2 is a vertical central View of myimproved apparatus, showing the interior elements arranged in operativerelation therein. Fig. 3 is a top plan view of the layers ofoil-separating bars.

Referring to the drawings, A designates a steam -cylinderg B, theengine-shaft; O, a steam-pipe leading into the steam-cylinder, and D anexhaust-steam pipe leading from the steam-cylinder into my improvedapparatus. These elements are illustrated conventionally and may be ofany approved construction and arrangement. The steam-cylinder shown isdesigned to represent a steamcylinder taking exhaust-steam from aprimary steam cylinder in a doubleacting steam-engine; but it isapparent that myimproved steam and oil separator may be advantageouslyconnected to the exhaust of a single-actin g engine.

In Fig. 2 is illustrated niyimproved steam and oil separator, the partsbeing shown in central vertical section, and, reference being hadthereto, l designates a casing, prefer-V ably cylindrical and of suchdimensions and capacity as will accommodate it to the pur- "poses anduses intended.

The casing or body is formed with annular iianges a b at its upper andlower ends, as shown, and at a convenient location adjacent to its lowerend is provided with an opening c, to which is fitted a steam-tightclosure (l, whereby access may be had to the interior for removingdepositions and cleaning the cylinder. The cylinder is provided with abottom 2, having an annular liange e coincident with the (iauge l), andthe bottom is made concave in its inner side to serve as a basin for thecondeusatious. The {ianges b and e are secured together by any properfastenings. A flanged cover 3 is secured over the casing, and arelief-valve f maybe placed in the cover. The casing thus made up ismounted 011 a suitable support 4. In the casing is placed a pipe 6,curved downward andprojecting toward the bottom of the casing.Theeutranceendofthepipeprojects beyond the face of the casing and isprovided with an annular flange g, adapted to he secured to the hangedend of the exhaust-pipe D. The pipe 6 may be held tight to the cylinderby inner and outer fianges h h and a suitable packing c' between theinner flange and the inner face of the casing. In the casing, at asuitable and determined distance above the bottom thereof, are arrangedlayers of hars 26, semicircular in cross-section and placed across thecasing in vertical series or layers, one above the other, with spacesbetween their side edges andthe spaces of lower layers being covered orstraddled by the bars of the next adjacent and succeeding layer, asshown in the drawings. The ends of the bars are supported on theinwardly extending flanges of bands 27, secured at intervals to theinner face of the casing. The nest or series of bars thus arranged andmounted cont IOO the tortuous passages between the said bars. In theupper portion of the casing is placed a dry pan or box 10, provided witha perforated cover or top K, through which the steam has access to thepan. Secured to the bottom of the dry-pan and opening therefrom is acurved exhaust-pipe 14,havingits lower en d extended through and beyondthe casing, as at l5, and is suitably formed to connect to a pipe (notshown) which leads to a condenser or heater for subsequent use in theboiler. The pipe 1l is held in position by oppositely-arranged ilanges'mn and interposed packing-ring, or in both instances the pipes 6 and 1lmay be secured in position by the flanges h and m and suitable packingbehind them and a couplingpiece then secured to the outer faces. Meansare provided for automatically discharging the accumulations ofcondensations of water and oil from the casing. In the bottom of thecasing is fitted a bushing or plug 2l, having the upper end groundtapering, as at 0, to form a seat for a sleeve, as hereinafterspecified. In the bushing 2l a vertical tube 2O is tted and held. Thistube is closed at its upper end and provided with an escape-port 25,placed closely adjacent to the upper end of the bushing 2l, so that thewater of condensation and the oil will escape and be discharged throughthe tube 20. On the tube 20, within the casing, is slidingly arranged asleeve 22, having its lower end shaped to fit tight down on the end ofthe bushing 2l to prevent leakage. The sleeve 22 is projected through alioat 23, so that the sleeve will be moved with the movements of thelioat. It will be perceived from the foregoing that when the products ofcondensation are belowr the escape-orifice the fioat will hold the endof the sleeve down on its seat on the end of the bushing, and thecondensations cannot escape; but when the condensations rise to lift thefloat, with the sleeve, above the escape-orifice the products ofcondensation escape and continue to discharge until by the descent ofthe fioat, with the sleeve, the escape-orifice is closed. To draw offwhatever of residuum may accumulate in the casing below the orifice 25 apipe 24. is provided, which leads into the lower end of the tube 2O andis provided with a suitable valvep to open and shut the passage throughthe pipe.

The operation of the apparatus is as follows: The exhaust-steam from theengine is fed through the pipe 6 and discharges into the casing into thechamber below the oil-separating bars, from which the steam rises, andlduring its tortuous passage through the nest of oil-separating bars isdeprived of the associated oils, which when accumulated sufficientlydrip into the lower part of the casing.

The steam continuing its upward course reaches the top or cover of thecasing, where it is deflected into the dry-pan through the perforationsin its cover and escapes comparatively dry and purified through the pipell to a condenser, heater, or, where desired, ready and cleaned for usein the boiler.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. A steam and oil separator, comprising a suitable casing, a nest oftransversely-arranged bars inthe casing laid in vertical series andhaving spaces between them, the bars of each succeeding layerintersecting the spaces of the layer below, a steam-pipe entering thecasing above and discharging below the nest of bars, a steam-boxdisposed in the upper portion of the casing having inlets in its top,and a steam-outlet pipe leading from the steam-box above the nest ofbars.

2. A steam and oil separator, comprising a suitable casing, a nest oftransversely-laid bars in the casing placed in vertical series andhaving spaces between them, the bars of each succeeding layerintersecting the spaces of the layer below, a steam-pipe entering thecasing above and discharging bclow said bars, a steam-box having aperforated cover or top, in the upper portion of the casing, and asteam-outlet pipe leading from the bottom of the steam-box through thewall of the casing.

3. A steam and oil separator, comprisinga suitable casing, a nest oftransversely-laid bars in the casing, semicircular in cross-section andplaced in vertical series with spaces between them, the hars of eachsucceeding layer intersecting the spaces of the layer below, asteam-pipe entering the casing above and discharging below the saidbars, a steamboX in the upper portion of the casing, having a perforatedcover, a steam-outlet pipe leading from the steam-box through thecasing, and means in the bottom of the casing to draw off the water ofcondensation and the oil. y

4. Asteain and oil separator, comprising a casing, separators arrangedtherein, a steampipe discharging beneath the separators, a steam-boxdisposed in the casing above the separators and provided withsteam-inlets, and a steam -discharge leading from the steam-box out ofthe casing.

In testimony whereof I affix my signature in presence of two witnesses.
